Barcelona, Spain — Sprint will be the exclusive U.S. outlet for the $399-suggested Harman Kardon Onyx Studio Bluetooth speaker, Harman announced at the Mobile World Congress.

Selling the disc-shaped portable speaker marks the first in a series of initiatives from Sprint this year to step up its audio assortment, Sprint said. The Onyx Studio will be available Feb. 25 for $399 exclusively in Sprint stores, the carrier’s online store, and through Sprint telesales for the speaker's launch, Sprint told TWICE.
